Rapid Thrombolysis Protocol: Results from a Before-and-after Study.

Objective: Intravenous thrombolysis within 4.5 hours from time of onset has proven benefit in stroke. Universal standard for the door-to-needle (DTN) time is within 60 minutes from the time of arrival of patients to the emergency department. Our rapid thrombolysis protocol (RTPr) was developed with an aim to reduce the DTN time to a minimum by modifying our stroke post-intervention processes. Materials and methods: This before-and-after study was conducted at a single center on patients who received intravenous thrombolysis in the emergency department. Consecutive patients who were thrombolysed using our RTPr (post-intervention group) were compared to the pre-intervention group who were thrombolysed before the implementation of the protocol. The primary outcomes were DTN time, time to recovery, and modified ranking score (mRS) on discharge. Secondary outcomes were mortality, symptomatic intracerebral hemorrhage, and hospital and intensive care unit length of stay. Results: Seventy-four patients were enrolled in each group. Mean DTN time in pre- and post-intervention group was 56.15 minutes (95% CI 49.98-62.31) and 34.91 minutes (95% CI 29.64-40.17) (p <0.001), respectively. In pre-intervention and post-intervention groups, 43.24% (95% CI 32.57-54.59) and 41.89% (95% CI 31.32-53.26) patients, respectively, showed neurological recovery in 24 hours. About 36.49% (95% CI 26.44-47.87) in pre-intervention group and 54.05% (95% CI 42.78-64.93) in post-intervention group had discharge mRS 0-2. Conclusion: The RTPr can be adapted by clinicians and hospitals to bring down the DTN times and improve outcomes for stroke patients.

Acute Effect of Caffeine-Based Multi-Ingredient Supplement on Reactive Agility and Jump Height in Recreational Handball Players.

Pre-exercise caffeine and guarana-based multi-ingredient supplement (MS) consumption may be more effective for physical performance improvement than caffeine and guarana alone due to the synergistic effect of biologically active ingredients in multi-ingredient supplements. This study aimed to examine the acute effect of MS on the reactive agility and jump performance in recreational handball male players. A randomized, double-blind, crossover study involved twenty-four male handball players (body mass 74.6 ± 8.8 kg; body height 179 ± 7 cm; age 23.8 ± 1.4 years). Participants were tested under three conditions: placebo, caffeine + guarana (CAF + GUA), or MS ingestion 45 min before exercise tests. Participants performed a reactive agility test (Y-shaped test) and countermovement jump (CMJ). None of the supplements improved countermovement jump height (p = 0.06). The time needed to complete the agility test was significantly (p = 0.02) shorter in the MS condition than in the placebo. The differences in agility between PL vs. CAF + GUA and MS vs. CAF + GUA conditions were not statistically significant (p = 0.88 and p = 0.07, respectively). The results of this study indicate that the caffeine-based multi-ingredient performance was effective in improvement in reactive agility but not in jump height in recreational handball male players. A similar effect was not observed with CAF + GUA ingestion alone.

Mucormycosis and COVID-19: An epidemic within a pandemic in India.

IMPORTANCE: Coronavirus disease (COVID-19) causes an immunosuppressed state and increases risk of secondary infections like mucormycosis. We evaluated clinical features, predisposing factors, diagnosis and outcomes for mucormycosis among patients with COVID-19 infection. METHODS: This prospective, observational, multi-centre study included 47 consecutive patients with mucormycosis, diagnosed during their course of COVID-19 illness, between January 3 and March 27, 2021. Data regarding demography, underlying medical conditions, COVID-19 illness and treatment were collected. Clinical presentations of mucormycosis, imaging and biochemical characteristics and outcome were recorded. RESULTS: Of the 2567 COVID-19 patients admitted to 3 tertiary centres, 47 (1.8%) were diagnosed with mucormycosis. Mean age was 55 ± 12.8years, and majority suffered from diabetes mellitus (n = 36, 76.6%). Most were not COVID-19 vaccinated (n = 31, 66.0%) and majority (n = 43, 91.5%) had developed moderate-to-severe pneumonia, while 20 (42.6%) required invasive ventilation. All patients had received corticosteroids and broad-spectrum antibiotics while most (n = 37, 78.7%) received at least one anti-viral medication. Mean time elapsed from COVID-19 diagnosis to mucormycosis was 12.1 ± 4.6days. Eleven (23.4%) subjects succumbed to their disease, mostly (n = 8, 72.7%) within 7 days of diagnosis. Among the patients who died, 10 (90.9%) had pre-existing diabetes mellitus, only 2 (18.2%) had received just one vaccine dose and all developed moderate-to-severe pneumonia, requiring oxygen supplementation and mechanical ventilation. CONCLUSIONS: Mucormycosis can occur among COVID-19 patients, especially with poor glycaemic control, widespread and injudicious use of corticosteroids and broad-spectrum antibiotics, and invasive ventilation. Owing to the high mortality, high index of suspicion is required to ensure timely diagnosis and appropriate treatment in high-risk populations.

Strength, Endocrine, and Body Composition Alterations across Four Blocks of Training in an Elite 400 m Sprinter.

The ability to produce force rapidly has the potential to directly influence sprinting performance through changes in stride length and stride frequency. This ability is commonly referred to as the rate of force development (RFD). For this reason, many elite sprinters follow a combined program consisting of resistance training and sprint training. The purpose of this study was to investigate the strength, endocrine and body composition adaptations that occur during distinct phases of a block periodized training cycle in a 400 m Olympic level sprinter. The athlete is an elite level 400 m male sprinter (age 31 years, body mass: 74 kg, years of training: 15 and Personal Best (PB): 45.65 s). This athlete completed four distinct training phases of a block periodized training program (16 weeks) with five testing sessions consisting of testosterone:cortisol (T/C) profiles, body composition, vertical jump, and maximum strength testing. Large fluctuations in T/C were found following high volume training and the taper. Minor changes in body mass were observed with an abrupt decrease following the taper which coincided with a small increase in fat mass percentage. Jump height (5.7%), concentric impulse (9.4%), eccentric impulse (3.4%) and power ratio (18.7%) all increased substantially from T1 to T5. Relative strength increased 6.04% from T1 to T5. Lastly, our results demonstrate the effectiveness of a competitive taper in increasing physiological markers for performance as well as dynamic performance variables. Block periodization training was effective in raising the physical capabilities of an Olympic level 400 m runner which have been shown to directly transfer to sprinting performance.

Effects of Co-Ingestion of ß-Hydroxy-ß-Methylbutyrate and L-Arginine α-Ketoglutarate on Jump Performance in Young Track and Field Athletes.

The aim of the study was to determine the effect of simultaneous supplementation of ß-hydroxy-ß-methylbutyrate and L-Arginine α-ketoglutarate on lower limb power and muscle damage in medium distance runners aged 15.3 (±0.9) years old. METHODS: The study group consisted of 40 volunteers aged 14-17 years practicing medium distance running for at least two years. The study lasted 12 days and followed a randomized, double-blind, placebo-controlled, parallel design. All subjects attended a familiarization session on day 0 before the test. The subjects were randomly divided into two groups: supplements and placebo group. The same training cycle protocol was used in both groups during the 12-day training period. Morning warm-up involved 10 min jogging at 60-75% of maximal heart rate and countermovement jump height measurement. Main training units were carried out for both groups with the same volume. Training load assessment (the daily session Rating of Perceived Exertion (s-RPE) method) method takes into consideration the intensity and the duration of the training session to calculate the "training load" (TL). RESULTS: At the end of the training cycle, a significant (p = 0.002) decrease in the countermovement jump (CMJ) height was found in the placebo group when compared to the baseline. In the supplement group, there was no decrease in the countermovement jump height. Creatine kinase and lactate dehydrogenase concentration increased during the training days similarly in both groups and decreased on rest days. There were no differences between groups in enzymes concentration. The research results indicate that the supplement combination used in the supplements group prevented a reduction in the CMJ values. In contrast to the supplements group, in the placebo group, the CMJ changes were statistically significant: a noticeable (p = 0.002) decrease in CMJ was noted between the baseline measurement and the 6th measurement. The well-being of the subjects from both groups changed significantly during the training period, and the intergroup differences in the mood level were similar and not statistically significant. CONCLUSIONS: The results of this study indicate that the daily co-supplementation with calcium salt of ß-hydroxy-ß-methylbutyrate (7.5 g) and L-Arginine α-ketoglutarate (10 g) during training might help to prevent decline in jump performance. No influence on muscle damage markers or mood was shown.

Effects of Pre-Workout Multi-Ingredient Supplement on Anaerobic Performance: Randomized Double-Blind Crossover Study.

BACKGROUND: The purpose of this research was to investigate the acute effects of a pre-workout supplement on anaerobic performance in resistance-trained men. METHODS: Twenty-three men underwent three randomized, double-blind testing sessions separated by a seven-day break. The participants performed three tests: isokinetic strength, three repetition maximum (3-RM) strength and Wingate. Statistical analysis was conducted in R environment. Linear mixed models were estimated via R package lme4. RESULTS: Mean T@0.2 s was significantly greater in supplemented condition for right and left knee flexors (PL: 103.2 ± 37.6 Nm; supplemented condition: 131.8 ± 29.3 Nm (p = 0.001)), and PL: 103.7 ± 39.3; supplemented condition: 129.4 ± 28.4 (p = 0.001)). T@0.2 s for right and left knee extensors (PL: 202.6 ± 58.6 Nm; supplemented condition: 237.2 ± 54.7 Nm (p = 0.001); PL: 203.3 ± 63.2 Nm, supplemented condition: 229.8 ± 50.8 Nm (p = 0.002)). Significant difference was in mean anaerobic power between supplemented and PL condition for right and left knee flexors (p = 0.002, p = 0.005) and for right and left knee extensors (p = 0.001 and p = 0.002). TTP was significantly shorter in supplemented condition for both sides knee flexors (p = 0.002). There was a significant difference for mean power in the Wingate test (placebo: 8.5 ± 0.6 W/kg; supplemented condition: 8.7 ± 0.5 W/kg (p = 0.038)). Mean 3-RM was significantly greater in supplemented condition (p = 0.001). CONCLUSIONS: The supplement significantly improves upper and lower body strength and power output in resistance-trained men.

Psychosomatic symptoms during South East Asian haze crisis are related to changes in cerebral hemodynamics.

OBJECTIVES: Forest fires in South Asia lead to widespread haze, where many healthy individuals develop psychosomatic symptoms. We investigated the effects of haze exposure on cerebral hemodynamics and new symptoms. We hypothesised that vasoactive substances present in the haze, would lead to vasodilation of cerebral vasculature, thereby altering cerebral hemodynamics, which in turn may account for new psychosomatic symptoms. METHODS: Seventy-four healthy volunteers were recruited, and serial transcranial Doppler (TCD) ultrasonography was performed to record blood flow parameters of bilateral middle cerebral arteries (MCA). The first TCD was performed in an air-conditioned environment. It was repeated outdoors after the participants spent 30-minutes in the haze environment. The prevailing level of pollutant standards index (PSI) was recorded. Appropriate statistical analyses were performed to compare cerebral hemodynamics at baseline and after haze exposure in all participants. Subgroup analyses were then employed to compare the findings between symptomatic and asymptomatic participants. RESULTS: Study participants' median age was 30 years (IQR 26-34), and new psychosomatic symptoms were reported by 35 (47.3%). There was a modest but significant decrease in pulsatility index (PI) and resistivity index (RI) in the left MCA after haze exposure (PI: p = 0.026; RI: p = 0.021). When compared to baseline parameters, haze exposure resulted in significantly lower mean PI (p = 0.001) and RI (p = 0.001) in symptomatic patients, but this difference was not present in asymptomatic patients (PI: p = 0.919; RI: p = 0.970). CONCLUSION: Haze causes significant alterations in cerebral hemodynamics in susceptible individuals, probably responsible for various psychosomatic symptoms. The prognostic implications and health effects of haze require evaluation in a larger study.

Transcranial Doppler: Techniques and advanced applications: Part 2.

Transcranial Doppler (TCD) is the only diagnostic tool that can provide continuous information about cerebral hemodynamics in real time and over extended periods. In the previous paper (Part 1), we have already presented the basic ultrasound physics pertaining to TCD, insonation methods, and various flow patterns. This article describes various advanced applications of TCD such as detection of right-to-left shunt, emboli monitoring, vasomotor reactivity (VMR), monitoring of vasospasm in subarachnoid hemorrhage (SAH), monitoring of intracranial pressure, its role in stoke prevention in sickle cell disease, and as a supplementary test for confirmation of brain death.

Contralateral reversed distal femoral locking plate for fixation of subtrochanteric femoral fractures.

PURPOSE: Subtrochanteric fractures of the femur are being managed successfully with various intramedullary and extramedulary implants with reasonable success. However, these implants require precise placement under image intensifier guidance, which exposes the surgeon to substantial amount of radiation. It also restricts the management of these fractures at peripheral centers where facility of image intensifiers is not available. Keeping this in mind we designed this study to identify if contralateral reversed distal femoral locking plate can be used successfully without the use of image intensifier. METHODS: Twenty-four consecutive patients (18 men and 6 women) with a mean age of 28 years (range 19-47 years) suffering subtrochanteric fractures of the femur underwent open reduction and internal fixation with reversed contralateral distal femoral locking plate. The outcome was assessed at the mean follow-up period of 3.2 years (range 2-4.6 years) using the Harris hip score. RESULTS: Twenty-one fractures united with the primary procedure, with a mean time of consolidation being 11 weeks (range, 9-16 weeks). One patient developed superficial suture line infection, which resolved with oral antibiotics. Another patient had a fall 3 weeks after surgery and broke the plate. Repeat surgery with reversed distal femoral locking compression plate was performed along with bone grafting and the fracture united. Two cases had nonunion, which went in for union after bone grafting. The mean Harris hip score at the time of final follow-up was 90.63 (range 82-97). CONCLUSION: The reversed contralateral distal femoral plate is a biomechanically sound implant, which when used for fixation of the subtrochanteric fractures with minimal soft tissue stripping shows results comparable to those achieved by using other extramedullary implants as well as intramedullary devices. The added advantage of this implant is its usability in the absence of an image intensifier.

Mini incision acromio-clavicular joint reconstruction using palmaris longus tendon graft.

INTRODUCTION: Conservatively managed acromio-clavicular dislocations leave the patients with significant disability. Various techniques have been described to manage such injuries operatively. However, all such techniques involve exposure of the coracoid and use of metallic implants. We present a series of eight patients managed with small incision and minimal soft tissue dissection using palmaris longus tendon graft. We treated eight patients (all males), with acute acromio-clavicular dislocation with a palmaris Longus tendon graft. MATERIAL AND METHOD: The mean age of the patients at the time of final follow-up was 28.5 years (range 26-29 years), and the mean follow-up was 18 months (range 14-28 months). Functional assessment was done as per the DASH scores, along with a self-evaluation of the results. The vertical acromio-clavicular distance at final follow-up was compared to that at the time of presentation. RESULTS: The mean DASH score at final follow-up was 3.01; on self-evaluation, all patients rated their result as good. The patients had no or minimal pain at final follow-up. The mean vertical acromio-clavicular distance reduced from a mean pre-operative baseline values of 10.26 ± 2-1.40 ± 0.855 mm at latest follow-up. DISCUSSION: This is a mechanically sound technique, which required a small incision and minimal soft tissue dissection. It also does not require exposure of the coracoid, thus almost ruling out chances of significant neuro-vascular injury. The patients did not require any second surgery for implant removal. However, a longer follow-up with a larger number of patients is required to evaluate its long-term results and stability of the repair. CONCLUSION: Acromio-clavicular reconstruction using the palmaris Longus tendon graft is a simple surgery worth trying by a surgeon not proficient in arthroscopic techniques.

Computed tomographic evaluation of the proximal femur: A predictive classification in displaced femoral neck fracture management.

BACKGROUND: Femoral neck fracture is truly an enigma due to the high incidence of avascular necrosis and nonunion. Different methods have been described to determine the size of the femoral head fragment, as a small head has been said to be associated with poor outcome and nonunion due to inadequate implant purchase in the proximal fragment. These methods were two dimensional and were affected by radiography techniques, therefore did not determine true head size. Computed tomography (CT) is an important option to measure true head size as images can be obtained in three dimensions. Henceforth, we subjected patients to CT scan of hip in cases with displaced fracture neck of femur. The study aims to define the term small head or inadequate size femoral head" objectively for its prognostic significance. MATERIALS AND METHODS: 70 cases of displaced femoral neck fractures underwent CT scan preoperatively for proximal femoral geometric measurements of both hips. Dual energy X-ray absorptiometry scan was done in all cases. Patients were treated with either intertrochanteric osteotomy or lag screw osteosynthesis based on the size of the head fragment on plain radiographs. RESULTS: The average femoral head fragment volume was 57 cu cm (range 28.3-84.91 cu cm; standard deviation 14 cu cm). Proximal fragment volume of >43 cu cm was termed adequate size (type I) and of ≤43 cu cm as small femoral head (type II). Fractures which united (n = 54) had a relatively large average head size (59 cu cm) when compared to fractures that did not (n = 16), which had a small average head size (49 cu cm) and this difference was statistically significant. In type I fractures union rate was comparable in both osteotomy and lag screw groups (P > 0.05). Lag screw fixation failed invariably, while osteotomy showed good results in type II fractures (P < 0.05). CONCLUSION: Computed tomography scan of the proximal femur is advisable for measuring true size of head fragment. An objective classification based on the femoral head size (type I and type II) is proposed. Osteosynthesis should be the preferred method of treatment in type I and osteotomy or prosthetic replacement is the method of choice for type II femoral neck fractures.

Ipsilateral simultaneous fracture of the trochlea involving the lateral end clavicle and distal end radius: a rare combination and a unique mechanism of injury.

Isolated trochlea fracture in adults is a rare surgical entity as compared to its capitellar counterpart. It has been only mentioned sporadically in the literature as case reports. Fracture of the trochlea is accompanied by other elbow injuries like elbow dislocation, capitellum fracture, ulnar fracture and extraarticular condylar fracture. Here we report a unique case of isolated displaced trochlea fracture associated with fractures of the lateral end clavicle and the distal end radius. We propose a unique mechanism for this rare combination of injuries: typical triad of injury, i.e. fracture of the distal end radius with trochlea and fracture of the lateral end of the clavicle. Nonoperative treatment is recommended for undisplaced humeral trochlea fractures; but for displaced ones, anatomical reduction and internal fixation are essential to maintain the congruous trochlea-coronoid articulation and hence to maintain the intrinsic stability of the elbow.

Long term results after surgical management of posterior wall acetabular fractures.

BACKGROUND: Posterior wall fractures are the most common of all acetabular fractures, and there is universal consensus that displaced fractures are best treated with anatomical reduction and stable internal fixation. Though early and mid term results for such studies are available, few shed light on long term results. This study was performed to evaluate long term functional and radiological outcomes in patients with posterior wall acetabular fractures and to determine factors that may contribute adversely to a satisfactory final outcome. MATERIALS AND METHODS: We retrospectively analysed the hospital records for patients who underwent open reduction and internal fixation (ORIF) for posterior wall acetabular fractures. Twenty-five patients (20 men, five women), including one with bilateral posterior wall fracture, with a mean age of 41.28 ± 7.16 years (range 25-60 years) and a mean follow-up of 12.92 ± 6.36 years (range 5-22 years) who met the inclusion criteria formed the study cohort. Matta's criteria were used to grade postoperative reduction and final radiological outcome. Functional outcome at final follow-up was assessed according to d'Aubigné and Postel score. RESULTS: Anatomic reduction was achieved in 22 hips, imperfect in four and poor in none. Radiological outcome at final follow-up revealed excellent results in ten hips, good in eight, fair in five and poor in three. The final d'Aubigné and Postel scores were excellent in 14 hips, good in six and fair and poor in three each. Patients with anatomical reduction had a favourable functional and radiological long term outcome. However, the presence of associated injuries in lower limbs and a body mass index (BMI) >25 adversely affected the final functional outcome. Osteonecrosis was seen in three patients, heterotopic ossification in two and Morel Lavallee lesion in one. One patient had postoperative sciatic nerve palsy, which recovered 6 weeks after surgery. CONCLUSION: Anatomic postoperative reduction leads to optimal functional and radiological outcome on long term follow-up; however, the presence of associated lower-limb injuries and BMI >25 adversely affects a satisfactory final outcome in patients with posterior wall acetabular fractures. LEVEL OF EVIDENCE: (Level 4) Retrospective case series.

Behavioural and psychological symptoms in poststroke vascular cognitive impairment.

BACKGROUND: Behavioural and psychological symptoms of dementia (BPSD) cause significant patient and caregiver morbidity in vascular cognitive impairment (VCI). Objectives. To study and compare the occurrence and severity of BPSD between multi-infarct dementia (MID), subcortical ischaemic vascular disease (SIVD), and strategic infarct subtypes of poststroke VCI and to evaluate the relationship of these symptoms with the severity of cognitive impairment. METHODS: Sixty patients with poststroke VCI were classified into MID, SIVD, and strategic infarct subtypes. BPSD were studied by the neuropsychiatric inventory (NPI). The severity of cognitive impairment was evaluated by the clinical dementia rating scale (CDR). RESULTS: 95% of cases had at least one neuropsychiatric symptom, with depression being the commonest, irrespective of subtype or severity of VCI. Strategic infarct patients had the lowest frequency of all symptoms. SIVD showed a higher frequency and severity of apathy and higher total NPI scores, compared to MID. Apathy and appetite disturbances occurred more commonly with increasing CDR scores. The total NPI score correlated positively with the CDR score. CONCLUSION: Depression was the commonest neuropsychiatric symptom in VCI. The neuropsychiatric profiles of MID and SIVD were similar. The frequency and severity of apathy and the net burden of BPSD increased with increasing cognitive impairment.

Fixation of delayed union or non-union posterior cruciate ligament avulsion fractures.

PURPOSE: To report the outcome of fixation for delayed union or non-union posterior cruciate ligament (PCL) avulsion fractures. METHODS: Seven men and 4 women aged 24 to 35 (mean, 28) years underwent lag screw or suture fixation for non-union or delayed union of avulsion fracture of PCL tibial attachment after a mean delay of 8.6 (range, 4-14) months. Patient satisfaction was assessed using a visual analogue scale (VAS). Functional outcome was evaluated using the Lysholm scale. RESULTS: The mean follow-up period was 17 (range, 8-36) months. The mean Lysholm score improved from 82 preoperatively to 92 at the final follow-up (p=0.34), the mean range of knee motion improved from 82º to 87º (p=0.008), and the mean VAS score for patient satisfaction improved from 4.3 to 7.4 (p=0.0004). All patients but one achieved bone union after a mean of 7.5 (range, 7-9) weeks. Functional outcome was excellent for 6 patients, good for 4, and fair for one. Posterior drawer test was positive (grade I laxity) in 3 patients whose outcome was good for 2 and fair for one. The latter had non-union after Ethibond suture repair for a communited fracture. There were no instances of wound complications or implant loosening. CONCLUSION: Fixation with lag screw or suture combined with bone grafting for delayed union or non-union of PCL avulsion fractures achieves acceptable functional outcome.

Longitudinal bracketed epiphysis of proximal phalanx of the great toe with congenital hallux varus managed simultaneously with monorail external fixator: a case report.

Longitudinal bracketed epiphysis (delta phalanx) is a rare congenital anomaly that affects phalanges in the hand more commonly than toes. We present a rare case of congenital hallux varus with longitudinal bracketed epiphysis of proximal phalanx with bifid distal phalanx of the great toe, which was managed with monorail type of external fixator. To the best of our knowledge, this is the first report of its successful implementation in simultaneous treatment of longitudinal bracketed epiphysis of the proximal phalanx of the great toe and hallux varus. Apart from adding to the literature a case of rare subtype of delta phalanx with hallux varus, the present study highlights the role of a reliable alternative in its management.

Cerebrovascular ultrasonography for selecting patients for stroke intervention.

Currently employed diagnostic ultrasonography provides clinically relevant information about cerebral hemodynamic changes in patients with cerebrovascular ischemia. The information thus obtained is often helpful to the physician for establishing or confirming the diagnosis and prognosis as well as in taking appropriate therapeutic decisions. It is associated with a high temporal resolution and can be performed bedside for rapid diagnosis as well as prolonged monitoring. Transcranial Doppler (TCD) ultrasonography is a non-invasive diagnostic modality that provides physiological information regarding various intracranial hemodynamic alterations in patients with cerebrovascular ischemia. Extended applications of TCD are useful in understanding various pathophysiological mechanisms responsible for the clinical manifestations of cerebrovascular ischemia. Thus, TCD is aptly called as the 'stethoscope' of a stroke neurologist. Cerebrovascular ultrasonography is considered as an essential component of a comprehensive stroke center. We have reviewed various recent patents pertaining to the applications of cerebrovascular ultrasonography employed in the selection of stroke patients for various therapeutic interventions.

Osteosynthesis with long volar locking plates for metaphyseal-diaphyseal fractures of the distal radius.

OBJECTIVE: Metaphyseal-diaphyseal fractures of the distal radius are a major treatment dilemma and orthopaedic surgeons have to pay due consideration to restoration of anatomy of distal radius together with rotation of the radial shaft and maintenance of radial bow and interosseous space. We performed this study to evaluate the clinic-radiological outcome of metaphyseal-diaphyseal fractures of the distal radius treated with long volar locking plates. METHODS: This prospective study involved 27 patients (22 males and 5 females) with metaphyseal-diaphyseal fracture of the distal radius. Their mean age was (30.12+/-11.48) years (range 19-52 years) and the follow-up was 26.8 months (range 22-34 months). All patients underwent open reduction and internal fixation with a long volar locking plate. According to AO/OTA classification, there were 7 type A3, 13 type C2 and 7 type C3 fractures. Subjective assessment was done based on the disabilities of the arm, shoulder and hand (DASH) questionnaire. Functional evaluation was done by measuring grip strength and range of motion around the wrist and the radiological determinants included radial angle, radial length, volar angle and ulnar variance. The final assessment was done according to Gartland and Werley scoring system. RESULTS: Postoperative radiological parameters were well maintained throughout the trial, and there was significant improvement in the functional parameters from 6 weeks to final follow-up. The average DASH scores improved from 37.5 at 6 weeks to 4.2 at final follow-up. Final assessment using Gartland and Werley scoring system revealed 66.67% (n equal to 18) excellent and 33.33% (n equal to 9) good results. There was one case of superficial infection which responded to antibiotics and another carpel tunnel syndrome which was managed conservatively. CONCLUSION: Volar locking plate fixation for metaphyseal-diaphyseal fractures of distal radius is associated with excellent to good functional outcome, early rehabilitation and minimal complications.

The profile of behavioral and psychological symptoms in vascular cognitive impairment with and without dementia.

OBJECTIVE: The objective of this study was to compare the occurrence and severity of behavioral and psychological symptoms of dementia (BPSD) between vascular dementia (VaD) and vascular cognitive impairment-no dementia (VCI-ND). MATERIALS AND METHODS: Consecutive patients presenting with cognitive impairment at least 3 months after an ischemic stroke and with a Hachinski Ischemic Score ≥4 were included. VaD was diagnosed as per National Institute of Neurological Disorders and Stroke - Association Internationale pour la Recherche et l'Enseignement en Neurosciences criteria for probable VaD and VCI-ND on the lines of the Canadian study of health and aging. The severity of cognitive impairment and the behavioral/psychological symptoms were studied by means of the clinical dementia rating scale and the neuropsychiatric inventory (NPI) respectively. RESULTS: All patients with VaD and 89% of those with VCI-ND had at least one BPSD. The mean no. of symptoms per patient and the total NPI scores were higher in VaD than in VCI-ND. Apathy and night-time behavior disturbances were significantly more common and severe in VaD. CONCLUSIONS: BPSD are very common both in VCI-ND and in VaD. The profile of BPSD is similar in both groups, albeit more severe in VaD. The net burden of BPSD is higher in VaD as compared to VCI-ND.

Double floating arm injury in a child: a case report and review of the literature.

The combination of ipsilateral humeral fractures at three different levels namely proximal, shaft and supracondyle has been rarely defined in the literature. We present a case report on such a complex injury in a 10-year-old child after falling down from the second floor of his house while playing. To the best of our knowledge, no such case report exists in the English literature. We define it as double floating arm injury. Firstly, shaft of humerus was open reduced and fixed with 4.5 mm narrow dynamic compression plate. Then closed reduction and pinning of the supracondylar humerus under an image intensifier was obtained. Open reduction using deltopectoral approach to the proximal humerus was done and the fracture was fixed with three K-wires. Ipsilateral multiple fractures in children often result from high energy trauma. Immediate reduction and fixation is required. Usually surgeons need to treat simple fractures firstly, which makes the subsequent treatment of complex fractures easier.
